Abstract
The present invention relates to finger authentication and improves a fingerprint authenticating function by excluding errors caused depending on detection forms. When a fingerprint is detected, form data representing the detection form are captured and, when inputted fingerprint data are compared with registered fingerprint data, authentication is executed referring to the form data. Thereby, the errors caused depending on the detection forms can be excluded and the fingerprint authenticating function is improved. A plurality of different detection form of fingerprint data are registered, a comparison target is selected from the fingerprint data, and the comparison target is compared with the inputted fingerprint data. Thereby, the fingerprint authenticating function is improved. To match the detection form, the apparatus may be configured to compare the registered fingerprint data with the inputted fingerprint data rotating either thereof and, thereby, similarly, the fingerprint authenticating function can be improved.
